This is the cathedral St Germain des Pres in the 6th arr. of Paris. Parts of it date from 500AD. It is across the street from Les Deux Magots, one of my two favorite cafes in Paris (Cafe des Flores, around the corner, is my other).
I’m not sure if the clock in the middle was working.
Leica M6 with 21mm lens. Hand held probably 1/30 due to the good lighting and 400ASA B&W film. The rangefinder is sooooo quiet!!!
